“Which size of fibroid is normal” refers to the typical range of uterine fibroid sizes most commonly seen in patients. According to USA Fibroid Centers, fibroids can be very small (about 1 cm, roughly the size of a seed) to quite large (over 10 cm, like a watermelon), but the average or typical range for many fibroids is about 5 cm to 10 cm in diameter. Size alone doesn’t always determine symptoms—location and number also matter—but fibroids in the 5 cm–10 cm range are generally considered within the typical size spectrum seen in clinical practice. https://www.usafibroidcenters.com/blog/fibroid-sizes/
